Major Changes:

• Engines have been changed from sending power on each pulse, to sending power on each tick.
  • In retrospect, I think this was a mistake - pulsed power works a lot better with axles (now BC 9.x) than with Kinesis Pipes (BC 8.x)
• Added kinesis pipe limits
  • Cobblestone Kinesis Pipes have a limit of 4 MJ/t
  • Stone Kinesis Pipes have a limit of 8 MJ/t
  • Wooden Kinesis Pipes have a limit of 16 MJ/t
  • Sandstone Kinesis Pipes have a limit of 16 MJ/t
  • Quartz Kinesis Pipes have a limit of 32 MJ/t
  • Gold Kinesis Pipes have a limit of 128 MJ/t
  • These limits are nearly identical to the previously unenforced limits, except Gold pipes have been buffed from 64 MJ/t
• Added the Diamond Kinesis Pipe
  • This is a limiter pipe, and can be switched between 256, 128, 64, 32, 16, 8, and 0 MJ/t.
• Added the Iron Kinesis Pipe
  • This is a limiter pipe, and can be switched between 32, 16, 8, 4, 2, 1, and 0 MJ/t
• Both Iron and Diamond Kinesis Pipes have gate actions to control them.
• Added a new Timer pluggable
  • This provides triggers for gates: 5 seconds, 10 seconds, and 15 seconds. (These are identical to their 1.7.10 counterparts)
  • This is made in an assembly table from a Clock
• Added a GUI to the tank.
• Changed Kinesis pipe texture to have a cyan inner border, rather than bright red.
  • There's also a configuration option to revert this, if you also disable the new RF pipes.
• Changed Creative Engine texture to be based on the command block
• Added optional (default enabled) Redstone Flux pipes
  • These are exact copies of regular kinesis pipes, but transmit Redstone Flux instead of Minecraft Joules.
  • These use a dark red inner border, somewhat similar to the previous kinesis pipe texture.
  • Crafted by adding redstone dust to a regular Kinesis pipe
• Added a configuration option to change the Minecraft Joules per Redstone Flux conversion rate
  • This has a default of 0.1 (1 MJ = 10 RF), a maximum value of 0.2 (1 MJ = 5 RF), and a minimum value of 0.0001 (1 MJ = 10,000 RF)
• Added optional (default disabled) MJ Dynamo
  • This converts MJ to RF using the above conversion rate
  • Default rate of consuming 4 MJ / tick, but this can be increased by adding up to 4 Iron and/or Gold Gears
• Added optional (default disabled) RF Engine
  • This converts RF to MJ using the above conversion rate
  • Default rate of producing 4 MJ / tick, but this can be increased by adding up to 4 Iron and/or Gold Gears
• Added a "Power Mode" configuration option, with 3 possible values:
  • "MJ_ONLY" - the current behaviour (and default). All BuildCraft machines and engines consume / produce Minecraft Joules, and the only conversion mechanism is the MJ Dynamo and RF Engine
  • "MJ_AUTOCONVERT_RF" allows all BuildCraft machines to accept RF, and makes engines produce MJ or RF depending on what they are powering
  • "DISPLAY_RF" is the same as MJ_AUTOCONVERT_RF but also displays (nearly) all power amounts in RF.

Changes:

• Changed minimum version of forge from 14.23.0.2544 to 14.23.1.2593
• [#4609] Added a config option "oilIsSticky" to configure whether oil acts like cobwebs.
• [#4700] Optimised wires (DaMatrix)
• Kinesis pipes now have a transfer delay of exactly 1 tick per block, rather than sometimes 0 or 1 ticks.
• Item Models for all Wooden, Iron, Diamond, Dazuli, and Emzuli pipes now use the filled texture on the bottom side.
• Added CraftTweaker compatibility for heatable and coolable fluids
  • Use mods.buildcraft.Refinery.addHeatable (or addCoolable) with parameters: input output int heatFrom int heatTo
  • Heat values should be between -10 and +20 (BuildCraft uses 0 ~ 3)
  • Fluid amounts are ignored (1 millibucket of input always produces 1 millibucket of output)

Bug Fixes:

• [#4656] Fix a NullPointerException in PipeFlowFluids (anonyco)
• [#4707] The distiller's "Has Work" condition is true even if the input tank doesn't have enough fluid to process.
• [#4708] The distiller's "Has Work" condition is true even if there's not enough room in the output tanks.
• [#4521] Fixed engines missing particle textures.
• [#4727] Fixed item pipes not keeping the "Items Traversing" trigger on during the same tick that they eject items into the next pipe.
• Fixed engines voiding power they couldn't send.
• Fixed fragile fluid shard items that contain a buildcraft heatable fluid having an extra "%s".
• Fixed not being able to place a pipe when a player is in the same block as the pipe (but not in the same bounding box as a pipe)
• Fixed pipes not having running particles.

Additions:

• API for setting pipe render state and pluggable state.

Bugs fixed:

• [#4712] Gate items not displaying in the relevant creative tab.
• Potential crash with Remote IO.

Bug Fixes:

• Fix the heat exchanger passing a null fluid when auto-outputting an empty tank.
• Fix kinesis pipes never configuring on the client, which cause client-side engine rotation to not work correctly.
• [#4385] Fixed the autoworkbench duping leftover tools.

Changes:

• Ported Engine Chaining:
  • Attach up to 3 stirling or 5 combustion engines together in a line to form a chain.
  • "Chained" engines send power directly to their destination.
  • Redstone engines cannot be chained.
• Ported the Gate Copier
  • This doesn't perform any validation on the copied triggers and actions at the moment.
  • It is made in an assembly table from a wrench and an iron chipset.
• Added oil generation debug logging:
  • Enable some logging by adding "-Dbuildcraft.energy.oilgen.debug=log" to your launch arguments.
  • Enable all logging (very spammy) by adding "-Dbuildcraft.energy.oilgen.debug=true" instead of the above to your launch arguments.
• Updated Chinese translation. (SampsonnZ)
• BuildCraftGuide[#2] Added some transport, silicon, triggers, and actions documentation to the guide book (LuigiHutch)

Bug Fixes:

• [#4553] Fix diamond pipes not considering IC2 cables with insulation the same non-insulated versions. (ashlanderr)
• [#4562] Fix odd crash when opening an assembly table.
• [#4568] Fix heat exchangers resetting whenever a neighbouring tile entity was changed.
• Potentially fixed a bug with wildnature.
• Removed log spam whenever a heat exchanger has fluids that cannot have heat exchanged between them.
• Hooked up the quarry config options added in 7.99.24.5 - so now they can actually be used.

Additions:

• Re-added the pipe traversing item filter parameter.
  • So now you can check if cobblestone is travelling through and item pipe specifically, rather than anything.

Localisation:

• Updated the Swedish localisation (Regnander)

Bug Fixes:

• [#4534] Fix an odd crash when trying to get collision boxes for a quarry.
• [#4543] Fix attempting to fill a nearly-full combustion engine with a water emmitting a lot of log messages.
• Fix dirty fuels outputting a quarter of the power that they should have been.
• Fix the quarry not working when it's battery went above 18,000 MJ.
